Erosion dominates among the degradation processes of chernozems (black soils) in Ukrainian. It covers 32% of the total area of agricultural land - 14.9 million hectares. The development of erosion processes depends on the combined effect of factors: climatic, geomorphologic, geologic (including the characteristics of parent rocks), hydrogeologic and technogenic impact. The purpose of the research is the analysis of natural and technogenic factors of chernozems degradation in Ukraine to develop the principles of pr...
